from tkinter import *
import decimal

twoD = int(0.80)
threeD = int(1.50)
gui = int(2.00)

root = Tk()

e = Entry(root, width=8)
e.pack()
e.get()

a = Entry(root, width=8)
a.pack()
a.get()

b = Entry(root, width=8)
b.pack()
b.get()

twoD_num = e.get()
threeD_num = a.get()
gui_num = b.get()

twoD_amount = twoD * twoD_num
threeD_amount = threeD * threeD_num
gui_amount = gui * gui_num

output = twoD_amount + threeD_amount + gui_amount

def myClick():
    myLabel = Label(root, text = output)
    myLabel.pack()
    print(output)

myButton = Button(root, text = "Calculate", command = myClick)
myButton.pack()

root.mainloop()```

when i output the numbers there is no value, i am trying to set it up as a money calculator type thing where the twoD = 0.8 as the price and then you times by the amount of products and add all of the products together the issue is that the output is blank

I think the problem is that you call a.get before you've typed anything into the entry

#

try this instead -- I can't tell if the output is right, but at least it displays something ```py
from tkinter import Button, Entry, Label, Tk

twoD = int(0.80)
threeD = int(1.50)
gui = int(2.00)

root = Tk()

e = Entry(root, width=8)
e.pack()

a = Entry(root, width=8)
a.pack()

b = Entry(root, width=8)
b.pack()

def myClick():
twoD_num = e.get()
threeD_num = a.get()
gui_num = b.get()

twoD_amount = twoD * twoD_num
threeD_amount = threeD * threeD_num
gui_amount = gui * gui_num

output = twoD_amount + threeD_amount + gui_amount

myLabel = Label(root, text=output)
myLabel.pack()

print(output)

myButton = Button(root, text="Calculate", command=myClick)
myButton.pack()

root.mainloop()

gotta say, your variable names are so bad that they are probably half your problem

When I was in junior high school, struggling with my math homework, my Dad helped me by telling me to write neatly and big. I thought that was so stupid; I was having trouble with the quadratic equation, not my handwriting!!

He was right.

And what about:

twoD = int(0.80)
threeD = int(1.50)
gui = int(2.00)

That's the same as:

twoD = 0
threeD = 1
gui = 2
